[QUOTE="shinbone, post: 1669099, member: 15248"] A person can shoot however many shots they want when checking for accuracy and call it good. It all depends on the person's goal. When checking a rifle or load for hunting accuracy, 3 shots can be good enough because that is probably more than will be shot when the gun is used in the field. With just 3 shots, however, a 3/4" group one day can easily be a 1-1/2" group the next. That is still "minute of deer," and still good enough for hunting, but that is hardly a reliable [I]measure[/I] of the gun's/load's true accuracy. When measuring a gun and/or load for accuracy, 5 shot groups are needed to reduce the group-to-group variation so the gun's/load's true accuracy becomes apparent. There will still be group-to-group variation with 5-shot groups, but it will be much smaller than with 3-shot groups. Of course, more than 5 shots will be even better, but there is a point of diminishing returns, and 5-shots is the generally recognized standard for such measurements. JMHO [/QUOTE]
